IMPROVEMENT IN STOVES FOR RAILROAD-CARS.

TO ALL WHOM IT MAY CONCERN:

Be itknown that I, I". II. WHITMAN, of Harrison, in the county ofCumberland, and'State of Maine, have invented a new and useful ImprovedVStove for Cars, die.; and I herehy declare the following to be a full,clear, and exact description thereof, which will enable othersv to makeand use my invention7 reference being` had to the accompanying drawings,forming pa'rt of this specification, in which- A. shows a side verticalelevation of a stove.

B, the exterior ofthe slide or draught.

C, the curtain in the same.

D E, views ofthe cam and shank to fasten the door. Y

Grreat disasters have resulted from the coals and lanics of the stovesused for heating cars being poured out, into the cars, when ythe samehave capsized in running ofthe track, and other accidents.v

Itl is the purpose of my invention to produce a stove from which, whenthe door is properly closed and secured, none of the fire can be shaken,even if the stove is turned over on one side, or completely eapsized.

It consists of a method of fastening the door, closing automatically thefunnel and grate,`or draught, when the stove is tipped or turned over oreanted either way.

a is the funnelnof the stove. b b are two studs, let down into the stovefrom the top, with heads c c. d is a plate, applied te the inside of thetop ofthe stove. e is a plate, suspended on the studs b b', and looselyhung, 'so as to slide up and down on `the same.

Suppose the stove to he turned upside down, then e will slide up on thestuds b b until it strikes the plate (l, and thus close up thefunnel-aperture, so if, in case of an accident, it, the stove, should beturned over orA thrown down, the sliding plate e will, when the stove isbottom side up, stop up the funnelaperturc.

The plates are represented somewhat convex, and this I consider the bestform; but am also aware that they may be inade Vconcave or dat'.

When the stove is standing properly, the plate e rests as indicated inthe drawing. v

This device will thus close the funnelaperture automatically, when thereis any danger, from the position ofthe stove, that tire or coals canescape through the funnel a.

B shows the slide, draught, or grate, as common, on the exterior, exceptthat the sliding slotted piece t will slide from side to side, so as toreadily close the small apertures of the grate, if and whenever thestove is tipped or inclined from side to side. This slide 7L movesautomatically; for instance if the stove is tipped toward l or 2, Fig.B, the slide t will more, so as to close the apertures, that is, it isfree to do eo. But there is another motion of the stove when tipping,which will not operate theslide 7i, that is, when the stove is so tippedas to bring the grate or draught B either on the top or bottom side ofthe stove, as it lies'after b eing thus tipped. Under .suchcircumstances, the slideh would not operate, and, if left open, firemight issue or coals drop out ofthe small apertures in the draught Toobviate this, I suspend the curtain C in the grate, on the inside of thesame, and makea lip or shoulder, 7c, on the inside of the stove.

Now, as you tip 'the stove either toward '3 or 4, itwill he seen by thedotted lines that the curtain will close the draught, swinging freely,as it does, on the pivct'm. If the stove is tipped toward 4, the curtainwill strike the part n ofthe draught; if in the opposite direction, itwill strike L". y

Thus, whatever way the stove is tipped, the draught is closed, either byslide 7i or curtain C.

The door I fastenby means of a cam, D, having a shank, E, projecting onthe outside, and operated by a removable wrench, so that the properofficer on the car can only operate the saure.

I ain aware of a patent for a fixed piece or sheet of metal placedacross the funnel-aperture in a` stove, but I do not claim such adevice. i

WhntI do claim as my invention, and desire to secure by Letters Patent,is.-

1.- The plate c, suspended on. plates Z1', so as automatically to closethe funnel-apertura., substantially as herein set forth.

2. The self-closing grate or draught, substantially as and for thepurposes herein set forth.
